Problems solved by technology

Among them, the filter laminate is the most important part of the laminated filter, which has a great influence on the filtering effect. If the structure design of the filter laminate is unreasonable, it is difficult to guarantee the overall filtering effect of the equipment, and it will not be able to meet the requirements for irrigation water. The purpose of precise filtering
[0004] The structure of filter laminations in the prior art is complicated, requires high manufacturing cost, and its backwashing effect is poor, which is not conducive to popularization and use

Embodiment approach 1

[0044] Such as Figure 1 to Figure 7As shown, the present invention provides a filter stack 6, which includes: a stack body 61, which has an inner ring wall 611 and an outer ring wall 612; a plurality of bending units 62, and a plurality of bending units 62 are arranged end to end in sequence On the upper surface of the lamination body 61, the bending unit 62 has a first partition wall 621 and a second partition wall 622, the first partition wall 621 and the second partition wall 622 are formed with a first inlet 63 at the outer ring wall 612, Two adjacent bending units 62 are formed with outlets 64 at the inner ring wall 611, and a plurality of diversion channels 65 are respectively opened on the first partition wall 621 and the second partition wall 622, and the plurality of diversion channels 65 communicate with the second partition wall. An inlet 63 and an outlet 64 . A plurality of bending units 62 is equivalent to a folded filter screen, and the filtering area of ​​a co...

Embodiment approach 2

[0104] The present invention also provides a laminated filter including the filter laminate 6 of Embodiment 1. The structure, working principle and beneficial effect of the filter laminate 6 are the same as those of Embodiment 1, and will not be repeated here.

[0105] Such as Figure 8 As shown, a laminated filter comprising the above-mentioned filter laminate 6 includes: a housing 1 connected with an inlet pipe 2, an outlet pipe 3 and a backwash pipe 4; a filter element holder 5 arranged on the Inside the casing 1, a plurality of filter laminations 6 stacked up and down are sheathed on the filter element holder 5. Specifically, the water inlet pipeline 2 , the water outlet pipeline 3 and the backwash pipeline 4 are respectively provided with valves, and these valves are used to open or close the water inlet pipeline 2 , the water outlet pipeline 3 and the backwash pipeline 4 .

[0106] In this embodiment, the laminated filter includes three sets of filter units, that is, th...

Abstract

The invention provides a filtering laminating piece and a laminated type filter. The filtering laminating piece comprises a laminating piece main body and multiple bending units; the laminating piecemain body comprises an inner ring wall and an outer ring wall; the multiple bending units are connected orderly end to end and arranged on the upper surface of the laminating piece main body; each bending unit is provided with a first isolating wall and a second isolating wall; the first isolating wall and the second isolating wall are formed with first inlets at the outer ring wall, and two adjacent bending units are formed with outlets at the inner ring wall; multiple guide flow channels are arranged on the first isolating wall and the second isolating wall, and connected to the first inletand the first outlet. The filtering laminating piece is simple in structure, good in filtering effect and has back flushing function; the laminated type filter with the filtering laminating piece canaccurately filter water flow, and the filtering efficiency is high.

Description

technical field [0001] The invention relates to a laminated sheet and a filter device, in particular to a filter laminated sheet and a laminated filter in the technical field of water filtration. Background technique [0002] At present, the laminated filter is a device used to filter the liquid containing impurities, especially in the field of agricultural irrigation, it is necessary to filter the large particles in the water, so as to obtain relatively pure irrigation water. [0003] Existing laminated filters are structurally generally composed of housings, filter laminates, laminated supports and other components. Among them, the filter laminate is the most important part of the laminated filter, which has a great influence on the filtering effect. If the structure design of the filter laminate is unreasonable, it is difficult to guarantee the overall filtering effect of the equipment, and it will not be able to meet the requirements for irrigation water. for precise fi...
